I have the looper but even though I have plugged it in it's not turning on ☹️

all i want it to do is make my guitar sound like it tuned down half step with out having a harmany effect or other effects will it do that?

Donner Harmonic Square does NOT have a halftone pitch settings, so the answer is no!
